HONING AND STROPFI'NG DEVICE.

Application filed October 17, 1927. Serial No. 226,698.

This inventio-n relates to new and useful improvements 1n honing andstropping devices.

In common practice, razors are honed and stropped by having the twostraps attached to some stationary object having a hook for engagementwith an eyelet turnably mounted in a clip thatiirmly holds the twostraps together at one end, while the free ends are held by t-he hand tokeep them in a taut position while the razor is being sharpened butshould the straps be too slack they may turn and by one st-roke thestraps are cut which eventually necessitates the replacement of thestraps by new ones.

It is one of the objects of the present invention to provide a honingand stropping device that will hold the straps in aA taut conditionthroughout the operation of sharpening a razor.

It is a further object of the invention to mount the straps in Vsuch amanner that they may be alternately turned and kept in the same tautcondition by the actuation of a push rod.

Another object of the invention is to provide a honing and stroppingdevice which does not necessitate the finding lof some convenient objectto hang one end to, during the stropping of .a razor. v

With these and other objects inview, the invention consists'in cert-ainnovel features, construction and combination of parts hereinafterdescribed and particularly pointed out in the claims, the advantages ofwhich will be readily understood and appreciated by those skilled in theart to which the. invention pertains.

The invention will be clearly understood from the accompanying drawing,illustrating the invention in its preferred form, and the fol-lowingdetailed description of the construction therein shown.

In the drawing e Figure 1 is a perspective view of my improved honingand stropping device.

Figure 2 is a vertical longitudinal sectional view taken on the line 2-2of Figure 1.

Figure 3 is a vertical transverse sectional view on the line 3 3 ofFigure 2.

Figure 4 is a' horizontal sectional view taken on the line 4 4 of Figure2.

Figure 5 is a detail perspective view of one of the T-shaped keys.

Referring more particularly to the drawing, the reference numeral 10designates my improved honing. and stropping-device in its entiretywhich includes an elongated base 1l having a U-shape brackete12 mountedon the upper face thereof. The ears 13 and 14 of the bracket constitutebearings or supports for a turnably/mounted stropping and honing element15 of aA construction now to be described. i

The stropping and honing element 15 consists of an elongatedl plate 16abutting a T- shaped key 19 at opposite ends and a` bearing nut 17 whichis turnablyA mounted in the ear 14 of the bracket and is fixed to thekey by a removable pin 18. The opposite end of the plate 16 also abutsthe inner end of a similar T-shaped key 19 which has its shank vextending through and fastened to a segmental gear 20 by a set screw 21.The gear 2O isy provided with a hub 22 which has its bearing on the ear13 of the bracket in axial alignment with the bearing nut 17 `mounted inthe opposite ear 1 4 thereof. e

Attached tothe plate 16 and the T-shape keys 1,9 are honing andstropping. straps 23 and 24 respectively, and which are removablyapplied for replacement when worn. In app-lying the above straps, plate16 is removed from its bearings and the adjacent ends are attached tothe keys 19 while in'an elongated condition by bolts 25. Interposedbetween the keys and the ends of thestraps are metal f washers 26 whilebendable .plates y27 are placed between the ends of the plate 16 and thestrap ends. The straps are then folded down and pulled taut softhat themetal plates 27 overlie the heads of the. bolts and retaining nuts toprevent wear between the bolt heads and nuts, and the straps. Theopposite ends of the straps are identically fixed and any slack whichmight have originally existed has been arrested.

For the purpose of actuating the element 15 to alternately reverse thestraps, I provide a sliding rack member 28, the teeth of whichy engagethe teeth of the gear segment 20. A housing 29 is removably applied tothe end of the base 11 and co-acts with the ear 13 for completelyhousing the gear segment and rack to exclude dust and dirt from theworking parts. For guiding the rack member 28 in its lateral movements,I provide a iange or rib 29 which projects from the outer face of theear 14 into a. groove 30 provided in the inner side face of the rackmember. Motion is imparted to the rack member by themanual actuation ofa push bar 31y extending from one of the sides of the base 11 and whichhas its inner end pivotally connected'to one end of a pivoted rock lever32V disposed Within a recess 33 in the base.A The llower end of the rackelement 28 is notched as at 34: for freely receiving the free end of therock lever to cause the same to be moved in opposite directions. A leafspring 85 is fixed to oneivall of the recess and has its free endabutting the side of the rock lever 32 to which the push bar 31 isconnected; The spring normally holds the ack member 28 in a position atthe limit of its movement in one direction so that the honing strap 23is `normally on top, as this is the `first strap to be used Whensharpening a straight blade razor. After the honing operation which isperformed by holding the device in one hand of the operator with histhumb on the manipulating end of the push Y bar 31, the operator pushesupon the push bar causing the actuation of the. rock lever 32 againstthe action of the spring ivhich in turn moves the rack member 28 to thelimit of its movement in an opposite direction, thus imparting a. halfrevolution to the stropper element through the actuation of the gearsegment 20. The stropper strap is now face up and may be used tocomplete the razor sharpening operation. When finished, the operatorreleases the pressure upon the push rod 31, whereupon the spring 35causes the parts to automatically return to normal position.

While I have described what I deem to be the most desirable embodimentof my invention, it is obvious that many of the details may be variedWithout in any Way departing from the spirit of my invention, and Itherefore do not limit myself to the exact details of constructionherein set forth nor to anything less than the Whole of my inventionlimited only by the appended claims.

lVhat is claimed as new is 1. In a razor sharpening device, a rotatablestropping element having different stropping surfaces on opposite sidesthereof, spring means normally holding one of said stropping surfacesface up, and manually operable means for imparting a turning movement tosaid rotatable stropping elcment against the action of said springmeansto reverse the position of said stropping surfaces, said last meansincluding a gear segment iixedly attached to` said stropping element,and slidable rack member co-acting therewith.

2. A razor sharpening device comprising a bracket, a stropping elementturnably mounted in said bracket and h aving different sharpeningsurfaces on opposite sides thereof, 'a gear segment on one end of saidstropping element, a slidably mounted rack member engaging said gea-rsegment, a rock lever having one of its ends extending` into a notch insaid rack member, and a push rod pivoted to the other end of said rocklever, substantially as and for the purpose specified.

A razor sharpening device comprisingl a bracket, a. stropping elementturnably mounted in said bracket and having different sharpeningsurfaces on opposite sides thereof, a gear segment on one end of saidstropping element., a slidably mounted rack member engaging said gearsegment, a rock lever having one of its ends extending into a` notch insaid rack member, and a. push rod pivoted to the other end of said rocklever, and a spring ac ting against said'rock lever to hold said rackmember at the limit of its sliding movement in one direction.

In testimony whereof I have affixed my signature.
